Slated for Sundance’s US Documentary competition section, director Marc Silver’s "3 1/2 Minutes" looks to be a harrowing exploration of criminal justice gone awry — and an all-too-timely film that speaks loudly to the current racial climate in America. (Trailer below.)

Here’s the synopsis:

In "3 1⁄2 Minutes," two lives intersected and were forever altered. On Black Friday in 2012, two cars parked next to each other at a Florida gas station. A white middle-aged male and a black teenager exchanged angry words over the volume of the music in the boy’s car. A gun entered the exchange, and one of them was left dead.

Michael Dunn fired 10 bullets at a car full of unarmed teenagers and then fled. Three of those bullets hit 17-year-old Jordan Davis, who died at the scene. Arrested the next day, Dunn claimed he shot in self-defense. Thus began the long journey of unraveling the truth. "3 1⁄2 Minutes" follows that journey, reconstructing the night of the murder and revealing how hidden racial prejudice can result in tragedy.
